Abstract

Un actionneur hydraulique comprend un logement de piston ayant une extrémité de tête et une extrémité de base opposée à l'extrémité de tête et un piston d'entraînement mobile entre une première position de piston à proximité de l'extrémité de tête et une seconde position de piston à proximité de l'extrémité de base. L'actionneur hydraulique comprend en outre une soupape de commande pouvant être positionnée entre une première position de soupape de commande, dans laquelle la soupape de commande dirige le fluide dans l'extrémité de base, et une seconde position de soupape de commande, dans laquelle la soupape de commande dirige le fluide dans l'extrémité de tête. Un système de rétroaction de position basé sur la pression est conçu pour faciliter la transition de la soupape de commande entre la première position de soupape de commande et la seconde position de soupape de commande en réponse à des pressions d'extrémité de tête et de base prédéfinies.
